I went back and tested 5 different servers that I usually use with 3 different maps between them, and unlike the past few days where I struggled to find a server I could play on, today the only server where I was getting the Auth message was a UGC server running mge_training_v8_beta4b. Two other servers running the same map let me play just fine. and I tested the same 5 servers an hour or two later and got the same results. I only use North American servers. It's as if the problem magically started to get better because I asked for help here

Starting a couple days ago almost everytime I join an MGE server and then try to join an area I am immediately kicked back to spectator and the following message appears in chat.

"Can't go in spec while in fight, removing from queue.
Your client has not been authed, please reconnect."

I've tried reconnecting to the server, restarting TF2, verifying the game files, logging out of and back into Steam, and restarting my computer, but nothing has worked to fix this so far. I also cannot access the item server while on MGE servers, so for the brief moment when in an arena I have an all stock loadout. This does not happen anywhere other than MGE servers specifically. I have no clue what caused this or how to fix it.
